[Ocfs2-users] Fence the node when out of quorum, make FS RO instead of restart?

[shencanquan]

Hi ,
I think it should not be  set to FS RO,  it should be set to not read 
and write. if it can be read, it will read the stale data.
when network partition, if not restart. how to deal the DLM domain. it 
may be has many DLM domain on single ocfs2 file system.

Thanks,
shencanquan
